It’s worth a few moments to get your bearings when using a new program. Or maybe you’ve been using SQL Developer Data Modeler for awhile now, and just haven’t taken the time to understand how designs, models, and diagrams are handled. This short post will fill in a few gaps and increase your comfort level with the tool, so please bear with me! Organization and Navigation Navigation is handled by the Browser. The Browser displays…
So you’ve been working on your data model, and you’re wondering how far ‘out of whack’ it is with the production or development database instance. Sometimes folks manage to compile changes into the database, bypassing your design process and rules. If you’re wondering how to compare 2 models instead of your model with the database, read this. So your question is basically, show me what’s different. You just need to decide what version of the…
Short and sweet post today – let’s say you’ve written a SELECT *, and your query results have some column headers you want to copy out. Yes, you could copy out the result set WITH the column headers, but maybe you JUST want the column names themselves. Note you need to select which column headers you want copied by selecting at least once cell in the grid. So in the screenshot above I have ctrl-clicked…
The end goal for many users of Oracle SQL Developer Data Modeler is a a nicely formatted, easy to read diagram. Diagrams are composed of two primary components: Tables or Entities Relationships Today’s post is all about how to manage the display of the relationships. How can I move the lines around? You might not like the default anchor point positions of the relationship lines. You can easily move these, but there’s a slight ‘trick.’…
Today’s question: Argh ! How can I remove the schema name from the relational diagram for a table in Sql Data Modeler ? Let’s take a quick look at the user’s source of frustration. I’ve previously reverse-engineered several Oracle schemas into a relational model in Oracle SQL Developer. HR and two other HR-Cloned users containing about 90 tables. Our user doesn’t want to see the “SCHEMA.” notation in the model diagram, but doesn’t want to…
Today’s Question: Does anyone know of an editor (or program) that will match beginning and ending parentheses in sql and highlight an ending paren that is missing? It just so happens that I do know of such an amazing editor or program 🙂 I’ll let the pictures do the talking for me this afternoon: Matched Parens Missing Parens Next question?
The Worksheet in Oracle SQL Developer is your primary interface for writing and running your SQL and PL/SQL code. As you can imagine, I’ve already written quite a bit about how the worksheet ‘works’. Today I want to spend just a few moments explaining the two different buttons for launching a new worksheet. With a worksheet open and active, you’ll see the following two buttons on two different toolbars: Doing a mouse-over shows me that…
I love it when I get product and technology questions from our users. More often than not, it leads to me citing a blog post on the subject, or even better, inspires new writing material. And that’s the case for today’s post: Is there an easy way to fake the search tool into getting all the tables in a design so I can export the column comments for everything? The CSV export does not appear…
A ‘quick’ question came in this morning: “Jeff, does SQL Developer show contents of Object type columns? I’m advised not…” I wanted to say ‘Yes’ and then just run away laughing maniacally, but I thought maybe I should put together a quick example instead. So here goes. And by the way, welcome to 2013 everyone 🙂 Creating a USER TYPE From the DOCS – 2054481983662a10560b1d2_000003 Create and Populate a Table using the new Type 2054481983662a10560b1d2_000004…
I’m frequently asked about books for SQL Developer. There are a few out there, with the most obvious example being from former Product Manager Sue Harper. I love books, and I’m a voracious reader. But books pose a few problems in the techie space: they are out of date the day they are printed they can be cost prohibitive – lots of pages and a small audience folks go to Google for answers now However…
